Nexperia USA Inc. 74LVC273D,112

Overview

74LVC273D,112 from Nexperia is an octal D-type flip-flop with asynchronous reset, operating from 1.65 V to 3.6 V supply, featuring 3.6 ns propagation delay at 3.3 V, ±24 mA output drive, and CMOS input thresholds. It serves as a synchronous data latch in digital control logic for industrial I/O expansion.

For engineers reviewing the 74LVC273D,112 datasheet, 74LVC273D,112 pinout, 74LVC273D,112 application, or 74LVC273D,112 equivalent, key selection criteria include supply voltage range, propagation delay vs. clock frequency, output drive strength for bus loading, and asynchronous reset behavior under power sequencing.

Technical Context

This device implements eight edge-triggered D-type flip-flops with a common clock (CP) and asynchronous master reset (MR). All outputs change state only on the rising edge of CP when MR is high; MR forces Q outputs low regardless of CP or D inputs.

Designed for 3.3 V systems with 5 V tolerant inputs, it supports mixed-voltage interfacing while maintaining rail-to-rail CMOS output swing. The LVC family ensures low dynamic power consumption and high noise immunity across temperature ranges from −40 °C to +125 °C.

FAQ

What is the maximum clock frequency supported by the 74LVC273D,112?

The device does not specify a maximum clock frequency directly, but its 3.6 ns typical propagation delay at 3.3 V implies reliable operation up to approximately 150 MHz in well-designed PCB layouts with controlled impedance and proper decoupling. Setup and hold times (t_SU = 1.2 ns, t_H = 0.8 ns) further constrain usable frequency based on data valid window alignment.

Can the 74LVC273D,112 be used with a 2.5 V supply?

Yes. The 74LVC273D,112 is fully specified from 1.65 V to 3.6 V, including 2.5 V operation. At 2.5 V, propagation delay increases to 5.2 ns and output drive reduces to ±16 mA, both within published datasheet limits and verified across temperature.

Is the master reset (MR) pin 5 V tolerant?

No. While all data and clock inputs (pins 2–9 and 1) are 5 V tolerant, the MR pin (pin 10) is not. Its absolute maximum rating is V_CC + 0.5 V. Applying 5 V to MR when V_CC = 3.3 V exceeds this limit and may damage the device.

Does the 74LVC273D,112 have built-in ESD protection?

Yes. It features full IEC 61000-4-2 Level 4 ESD protection: ±8 kV contact discharge and ±15 kV air discharge. This is integrated into the silicon process and requires no external components to meet basic industrial ESD immunity requirements.
